Break out stack(9) from ddb(4):
- Introduce per-architecture stack_machdep.c to hold stack_save(9). - Introduce per-architecture machine/stack.h to capture any common definitions required between db_trace.c and stack_machdep.c. - Add new kernel option "options STACK"; we will build in stack(9) if it is defined, or also if "options DDB" is defined to provide compatibility with existing users of stack(9). Add new stack_save_td(9) function, which allows the capture of a stacktrace of another thread rather than the current thread, which the existing stack_save(9) was limited to. It requires that the thread be neither swapped out nor running, which is the responsibility of the consumer to enforce. Update stack(9) man page. Build tested: amd64, arm, i386, ia64, powerpc, sparc64, sun4v Runtime tested: amd64 (rwatson), arm (cognet), i386 (rwatson)
